Diagnostic direction: Assessment of gas exchange, acid-base balance, function of the respiratory and metabolic systems of the body, disorders of water-salt balance.

Blood gas and electrolyte studies are important for assessing body function, in particular for monitoring the state of oxygen-gas exchange, acid-base balance, as well as the level of essential electrolytes, such as sodium, potassium, calcium. This study is used to assess the condition of patients in critical and unstable conditions, such as heart and respiratory failure, shock, renal failure, intoxication.

Indications for appointment:

• Discrepancy of clinical picture with laboratory indicators
• In case of need to monitor gas exchange and acid-base balance, as well as electrolyte and lactate levels
• Urgently (up to 30 minutes after receiving the result of the preliminary service order)

Biological material: arterial or venous blood, using a special syringe with lithium heparin

Performance time: 5 minutes (the result is received in the EMB after 15 minutes).
